NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, "AVSpare Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on AVSpare products.

Dispose of all fluids according to local regulations and mandates.


Note: Certain AVSpare machines may be equipped with the optional transmission oil pressure switch for brake application. If your machine is equipped with the optional pressure switch, a loop wire needs to be connected to the wiring harness to enable the brake release function to operate.

ReferenceFor further information on the transmission oil pressure switch for brake application refer to Systems Operation, Testing and Adjusting, "Parking Brake (Automatic Function)" for the machine that is being serviced.

    (1) Transmission oil pressure switch for brake application

    (2) Loop wire

    Note: Perform Step 1 and Step 16 of the following procedure only to machines fitted with transmission oil pressure switch for brake application (1) .

  1. Disconnect the transmission wiring harness from transmission oil pressure switch (1) at the electrical connector. Connect loop wire (2) between the EL331 BLUE wire and the EL330 GREY wire of the transmission harness, as shown.

    212-6102 Portable Hydraulic Pump

    (3) Plug

  1. Connect plug (3) of the 212-6102 Portable Hydraulic Pump to the machine's 24 volt DC power supply.

    Note: The machine batteries must be fully charged for the operation of the portable hydraulic pump. If battery charge is low, connect to an external 24 volt DC power supply.

  1. Release the braking system oil pressure.

    ReferenceRefer to Systems Operation, Testing and Adjusting, "System Pressure - Release" for the machine that is being serviced.

  1. Move the joystick control lever several times through the full range of travel. This will relieve any pressure that may be present in the implement hydraulic system.

  1. Move the STIC steering control lever several times in both directions to release any pressure in the steering system.

  1. Press and hold the breaker relief valve to release any pressure in the hydraulic tank.

    NOTICE

    Operating the portable hydraulic pump for extended periods of time may cause overheating and possible damage of the electric motor. If overheating is observed, stop operating the portable hydraulic pump and allow it time to cool before towing is continued.


  1. Press and hold brake release switch (6) in the ON position to activate the portable hydraulic pump. Brake accumulator oil pressure indicator (8) will go out when the braking system has full oil pressure.

    Note: Operation of the brake release switch should only take place from inside the operator station. Observe brake indicators and gauges while operating the portable hydraulic pump.

  1. When the braking system has full oil pressure, move parking brake control switch (9) to the OFF position to disengage the parking brake. Hold brake release switch (6) in the ON position until parking brake indicator (7) on the AVSpare Monitoring System panel is out. The parking brake is now disengaged.

    Note: The service brakes can be used to stop the machine when the machine has brake oil pressure. Use the service brakes to control the machine when the machine is being towed.

    Note: For the removal of the portable hydraulic pump from the machine refer to Steps 13 through 15.

  1. Repeat Steps 3 through 6.

  1. Disconnect and remove the portable hydraulic pump from the machine.

  1. Install the plugs on quick connect couplers (4) and (5) .
